Pre-fab Heat Interface Unit

RC version for domestic hot water and direct heating with radiator connection (no mixing circuit). Mixing circuit can be upgraded by using the dedicated cabinet with installed UFH mixing group (Uponor Combi Port M-Base Cabinet+manif IW-UFH). Bypass function can be upgraded by using special accessory - Uponor Combi Port M-Base Heat Bypass.
